The Obama campaign fires back at Mitt Romney over the Keystone pipeline, with campaign spokesman Ben LaBolt saying in a statement: “Mitt Romney has made clear that he would rubberstamp whatever the Republicans in Congress demand of him, whether it’s a budget that would make the middle class and seniors foot the bill for more tax breaks for the wealthiest or refusing to evaluate how a pipeline would affect our public health and natural resources. President Obama has pursued a comprehensive energy strategy that has increased our domestic energy production, reduced our dependence on foreign oil to below 50% for the first time in 13 years and supported more than 224,000 clean energy jobs.”
